摘要:Ultra-High-Definition (UHD) broadcasting, which is one of advanced broadcasting technologies, has met the users needs for high-definition and realistic services. By the way, UHD content is too large to be transported due to the limited bandwidth of existing HD broadcasting systems. In order to solve this problem, a lot of advanced broadcasting technologies have been suggested. One of the related researches proposed a UHD broadcasting service that each layer of video separated hierarchically are transmitted over heterogeneous networks. Unlike the existing MPEG-2 TS based on stream mode, UHD contents are transmitted based on packet mode. Therefore, to ensure the Quality of Service (QoS) of UHD content against inevitable packet delay, the UHD broadcasting system has to be taken into account the priorities of transmission depending on type of media and the layers of video simultaneously. In this paper, we propose a media-aware transmission method and also experimental results will be shown to verify the effectiveness of the proposed method.
